I have been following along with the Aaron Skonnard videos on creating a WCF service. I have completed the tutorial found here and when finished the WSDL page that would normally be available to a consumer of this service is not found (page states that "Endpoint is not found").
I have found many references to this issue including adding a 'mex' endpoint, adding httpGetEnabled, etc. but nothing seems to work. I believe this is because the tutorial removes the service files from the website code behind and instead uses a reference to another project.
I like the way the service is created with this tutorial but need to know how to get this WSDL page to display properly so others can consume my service. Is this no longer the correct way to create services in .NET 4?
I don't think REST based services (WebAPI) create a WSDL at all. I beleive the WSDL is only for the SOAP based WCF services.

I have consumed several wsdl services successfully, but am stuck now with this web service.
Am implementing Hotelston webservice which state :Hotelston.com API is a standard SOAP Web Service (WS) available at URL
http://www.hotelston.com/ws/HotelService?wsdl
I cant access the direct code of the webservice after i added the it as a reference in my application.
Please see the following MSDN articles for the exact details on how I added and used these web service references but still cant access it from the direct code.

If you show all files in the project and expand the service reference out, Reference.cs is empty. This is likely because there are namespace errors in HotelService.wsdl ("ax23", specifically) that is causing the t4 template to fail to generate the service code. Bottom line, it's their fault, not yours.
I am going to need a web service that receives a string via HTTP POST and processes it without any response to the client. However, since I'm not the one making the client (which will be cell phones) I am unable to use a generated client class to consume the service. The service would also need to be self hosted in a regular Windows service, if that matters.
As I'm not too experienced with web services nor WCF, I am frankly unsure if I can or should use WCF for this, but as it's the only type of web service I'm at least a little familiar with I figured it would be great to start out with one if at all possible.
I've been googling around quite a bit but haven't been able to find any good references to this, so I'd also be very grateful if someone has a link lying around to someplace that discusses it.
I think you need WCF Restful service with one way operation. Following link might help you:
A Developer's Guide to the WCF REST Starter Kit,
I am trying to access a webservice from my server using this tutorial consume web services.. i have been successful in accessing the web service and retrieving a string from it. but in most of the tutorials i have come across we need to give the method names in the web service thru the SOAP actions.. Is there any way in which we can even retrieve the methods that are present in the web service first within our application and then access it using those methods,, so the web service will be more flexible then and we can add more methods later??
You can use WSDL from service and generate proxy. WSDL contains service methods list. Check this
The first thing that springs to mind is to hit the WSDL definition, and search through it for the messages and data types you want.
I've been told that adding an HTTP RPC web service given an existing SOAP web service implemented with WCF is as simple as adding a webHttpBinding and a couple of attributes.
I'd be grateful if someone could show how to implement such an HTTP RPC web service using webHttpBinding given an existing SOAP web service that is based on WCF. It would be super helpful if the answer could show all the code for both services and even more helpful if the example is self-contained so that someone could install for testing without having to know anything about either. FYI, while I have programmed on the .NET stack it's been ~5 years and today all my work is on LAMP so I'm just not familiar enough with the latest generation .NET stack or it's current runtime environments.
My specific use-case is a set of two (2) services where one responds with an AuthToken and then a second service where I pass the AuthToken and Username, Password and another bit of information and the response back is a user object with attributes like 'first_name', 'last_name', etc. Ideally I'd be able to access those same services via two different URLs and the responses I would get back would be in JSON format.
Note I'm looking for an example to be installed by someone else who programs on the .NET stack but isn't highly motivated to do won't much extra work. I'm trying to get an HTTP-based web service I can use without having to add a SOAP client to the existing PHP framework I am using and I think if I could get a concise example of how to add such an HTTP RPC web service the .NET programmer might be happily willing to add the HTTP RPC web service for my needs. FYI, the web service in question was developed specifically for this use case and is not part of a standard set of SOAP services documented for and in use by lots of other developers.
Probably missing something very basic. I created a WCF 4.0 Rest Service. It works no problems when I'm hitting the url from a browser and I'm getting back what I want.
But now I want to use that service from a client mvc application (it will also be used by other non .net platforms which is why it's a rest service in the first place).
Problem is how do I get a service reference to it so I can start to use it in my c# code? With the new minimal WCF .net 4 config approach and no interface for the service contract, I don't know how to specify a mex endpoint. Ultimately I don't want a mex endpoint in production, just during development. I would love to be able to specify that all my services (around 10 in one application) have endpoints with one tiny piece of config that vs2010 .config transformations just rips out when I publish.
Stop. REST service doesn't use metadata. Metadata (Mex endpoint) are only for SOAP services because WSDL 1.1 (the only version supported by WCF) is able to describe only SOAP service. WADL or WSDL 2.0 is able to describe REST service but non of them is currently supported by WCF.
REST service is consumed by using WebRequest directly or by building ChannelFactory on top of shared contracts. Both methods are described here. Other method is to use HttpClient from REST Starter kit (former API). The problem with Starter kit is that it has never reached RTM (it was replaced by WCF 4). Instead of metadata endpoint WCF 4 REST service offers help page where all operation are described. When using WCF 4 REST template the help page should be already turned on - just add /help sufix to address of your service. Here is another article about building REST clients.
